P0174 FORD - Fuel Injection System Too Lean Bank 2.... Possible causes - Intake air leaks - Faulty front heated oxygen sensor - Ignition misfiring - Faulty fuel injectors - Exhaust gas leaks - Incorrect fuel pressure - Lack of fuel - Faulty Mass Air Flow (MAF) sensor - Incorrect Positive Crankcase Ventilation (PCV) hose connection Tech notes The codes is usually set when there is an intake leak after the air flow meter, before replacing any parts check for loose or broken hoses and intake gasket leak. On Ford some models dirty air filter, and dirty or faulty air flow sensor are the cause of the problem. It's a very common problem for the Ford Windstar. 1999-2003 Fords Windstar Code P0174. The problem is with the rubber grommets in the intake manifold bolts they will crack and cause an intake leak.
